GORDON V/ARD PULVER, OF BRANCH PCRT, NEW YORK.

LEAF-TURNER.

Application filed July 25, 1916.

T0 (ZZZ whom it may concern.

Be it known that I, GORDON VVARD Pun visit, a citizen of the United States, residing at Branchport, in the county of Yates, State of New York, have invented certain new and useful Improvements'in Leaf-Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in leaf turners, and has for its object to provide adevice of this character especially adapted for use in connection with pianos, whereby the same can be actuated, either by the foot or hand, to successively turn leaves.

A further object of the invention is to provide a leaf turner provided with spring actuated means for turning the leaves as desired.

lVith these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a front view of the device.

Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Fig. 4 is a sectional view on line 44 of Fig. 2.

Fig. 5 is a sectional view on line 5-5 of Fig. 2.

Fig. 6 is a sectional detail view of the latch.

Referring to the drawing 1 indicates a casing which is secured to the piano in any suitable manner and has mounted therein a frame 2, said frame serving to support the horizontal driving shaft 8, and connected to the driving shaft 3 is an operating spring 4:, which is anchored to the frame 2, whereby the spring can be wound upon rotating the key 5 carried by its outer end.

A ratchet wheel 6 is carried by the driving shaft 3 while freely mounted on the driving shaft 3 is an operating wheel 9. The ratchet wheel 6 is intended to rotate the operating wheel 9 through the medium of a pawl 8 which is pivoted to the operating wheel 9. This pawl is held in engagement with the Specification of Letters Patent.

Serial No. 111,199.

ratchet wheel by means of a spring 7 which is secured at one end to said operating wheel.

A plurality of non-alined arcuate racks 10, 11 and 12 are carried by the operating wheel 9, the purpose of which will appear later.

Rotatably supported by the frame 2 is a rod 13, the upper end of said rod terminating in an arm lat which is provided with an arm 15, said arm having leaf engaging clips 16 carried thereby. The lower end of the rod 13 is fixed to the mutilated gear 17, and disposed above the mutilated gear 17 are mutilated gears 18 and 19, the gear 18 having a sleeve 20 which engages in the sleeve 21 carried by the gear 19. The sleeve 20 is fixed to the rod 13 so as to properly hold the same. The sleeves 20 and 21 are provided with arms 22 both of which being provided with arms 23 which carry the leaf engaging clips similar to the leaf engaging clips 16.

Carried by the casing 1 is a latch 25 which can be operated by hand, or if desired a cord 26 can be attached thereto so that the latch can be actuated to release the wheel 9 upon operating a pedal (not shown).

It will be noted that the arcuate racks are normally disengaged from the gears, but when the latch 25 is actuated to release the operating wheel the rack 10 will engage the gear 19, thereby rotating the same and associated sleeve. It is of course obvious that the gears 17, 18 and 19 contain a suflicient number of gear teeth to permit eflicient operation of the racks 10, 11 and 12 at all times.

The operating wheel 9 is provided with a plurality of sockets 27 which are adapted to successively engage the arm 28 of the latch 25, thus limiting the rotation of the respective gears, said operating wheel being also provided with a knob 29 which can be grasped to hold the operating wheel while the spring 4 is being wound by the key 5.

In operation, when it is desired to turn a leaf, the cord 26 is pulled downwardly so as to operate the latch 25, whereupon the operating wheel 9 through the medium of the ratchet 6, pawl 8 and operating spring 4, will rotate, thereby causing one of the racks 10, 11 or 12 to engage one of the gears 17, 18 or 19 as the case may be and turn the desired leaf. When all of the leaves have been turned and it is desired to return the leaf engaging arms 15 to their former positions, the cord 26 is pulled downwardly so as to operate the latch 25. The knob 29 is then grasped by the operator and the operating wheel 9 rotated in the opposite direction, so that the racks 10, 11 and 12 will engage the gears 17, 18 and 19 and move them to their former positions. While the operating wheel 9 is returning the leaf engaging arms to their former positions, the pawl 8 moves freely over the ratchet wheel 6. When the different parts have been returned to their former positions, the

cord 26 is released so as to permit the latch to engage one ofthe sockets 27 in the operating wheel 9 so as to prevent the latter from rotating until the latch is actuated by the operator; 7

What is claimed A lea-fturner of the class described comprising a casing, a frame mounted in the casing, a driving shaft supported by the frame, an operating springsecured to the driving shaft and to the frame for rotating said shaft, a ratchet wheel carried by the driving shaft, an operating wheel freely mounted on the driving shaft, a plurality of non-alined arcuate racks carried by the operating wheel, a plurality of sockets carried by the operating wheel, a pawl pivoted to the operating wheel and resiliently urged into engagement with the ratchet wheel so as to transmit power to the operating wheel, a driven shaft supported by the frame, a plurality of mutilated gears carried by the driven shaft and intended to successively engage the arcuate racks on the operating wheel said gears and racks being positioned adjacent and in proximity to one another,

means carried by the gears for engaging leaves, locking means for engagement with the sockets in the operating wheel to prevent rotation of said wheel and releasing means for releasing said locking means.

In testimony whereof, I affix my signature. in the presence of two witnesses.
